Motor Control Center (MCC) Enclosures Give Your Engineers Centralized Control
A motor control center (MCC) consists of single or multiple enclosed sections grouped together for larger application requirements. These assemblies allow engineers to control electric motors in a central location. Typically found in large industrial buildings, these setups can include motor starters, circuit breakers, programmable controllers, metering equipment, and more. Any facility that operates a large number of electric motors may have use of MCCs, including the automotive industry and different commercial installations. At Porta-King, we supply the enclosure that protects MCC equipment.
At Porta-King, Fully Fabricated Structures with Custom Options are Just the Beginning
We offer benefits that other manufacturers just can’t match:
- Our buildings ship to site fully fabricated and ready for use. We also offer a modular designed system that is assembled onsite for interior applications.
- Our prefabricated assemblies are typically equipped with lifting lugs or rigging points in the floor structure to facilitate installations by crane or other lifting equipment.
- We can either ship to the final destination for the MCC equipment or to a staging area, so the MCC equipment can be installed and tested prior to being shipped to the final destination.
- Because we operate in a very large manufacturing plant, we can also facilitate installation of the MCC equipment at our facility.
- We offer a wide range of construction options to address different application requirements.
- Our engineers provide high quality workmanship along with our heavy duty construction features to ensure our enclosures will last for decades with little or no maintenance.
- For added protection in isolated locations, we offer ballistic rated construction.
- All floor plans are custom designed to meet application requirements.
- Code compliance for any destination in North America.
- Our custom building options include the following:
- Ballistic-rated materials
- Faux stone, brick, concrete composite siding, and custom paint finishes
- Sloped, gabled and other custom roof designs
- Custom architectural design enhancements for walls and roof structure
- High security locks and door hardware
- Large, multi-section designs to create larger enclosures

Motor Control Center Enclosure FAQs
What are the climate control options for motor control center enclosures?
Climate control is critical for protecting motor control center enclosures and their sensitive equipment. These enclosures can be equipped with various climate control options including thru wall, roof mount, ductless split systems, and wall pack units for heating and cooling. Motor control center enclosures can also incorporate exhaust fans, louvers, and dampers to manage air circulation when necessary.
Do motor control center enclosures meet local codes?
Code compliance for motor control center enclosures encompasses various requirements including wind and snow loads, seismic conditions, and energy efficiency. We recommend consulting local building officials about your plans to use a preassembled motor control center enclosure. We can support your compliance efforts with construction details and, for an additional charge, provide engineering calculations and energy code calculations for motor control center enclosures.
Do motor control center enclosures require a floor?
No, most motor control center enclosures don’t include floor structures since they often cover existing equipment. The rigid design of our motor control center enclosures maintains structural integrity without requiring a floor system.
What is the maximum height available for motor control center enclosures?
Motor control center enclosures can achieve a maximum interior clear height of 12 feet. The actual clearance for your motor control center enclosure will depend on specific design criteria. We recommend consulting with our project specialists to discuss your application requirements and determine the optimal design options for your motor control center enclosure.
Can power connections be made through the roof of motor control center enclosures?
For motor control center enclosures, we discourage on-site roof penetrations as this voids the warranty. Any necessary roof penetrations for equipment are made and weather-sealed at the factory. Power connections for motor control center enclosures typically enter through factory-created openings in other locations.
What door options are available for motor control center enclosures?
Motor control center enclosures offer various door options to accommodate specialized needs. While single and double man doors are most common, motor control center enclosures can also feature sliding doors, roll-up doors (manual or automatic), or framed openings for on-site door installation.
Are motor control center enclosures fire-rated?
While our motor control center enclosures are constructed of welded steel (Durasteel and Durasteel ES), they do not carry a specific fire rating as we do not have test data confirming FR classification.
What size limitations apply to motor control center enclosures?
Single-piece motor control center enclosures are limited to 15′ wide by 26′ long for structures between 10′ and 13′ tall, or 15′ wide by 48′ long for structures up to 10′ tall. These limitations are based on specialized transportation requirements. Larger motor control center enclosures can be created by connecting individual modules on-site.
Do motor control center enclosures include lifting lugs?
Durasteel ES model motor control center enclosures include standard lifting lugs on each corner. Other motor control center enclosure designs can be equipped with lifting lugs as an option. When lifting lugs aren’t suitable, crane lifting pockets can be incorporated into the base frame to facilitate lifting strap use.
Are motor control center enclosures insulated?
While our base Durasteel ES motor control center enclosure design features an uninsulated single layer of 16-gauge steel, most motor control center enclosures include insulation in walls, roof, and optional floor structures. Insulation helps protect internal equipment and reduces exterior noise levels.
